Anaal Nathrakh

This British duo has been making waves ever since their 2001
debut, The Codex Necro.
Anaal Nathrakh's style is best described as post-apocalyptic
black metal, with nightmarish shrieking vocals, monstrous wall-of-sound
guitar riffing, inhuman drumming (literally -- a well-done
drum program is used here) -- this is one exhaustive listen.
The various effects sprinkled throughout make it tempting to call
this industrial black metal, but that would be misleading as an
end-all description.
This duo is bludgeoning, cold, harsh, and unrelenting.
For many, that might be enough to propel Anaal Nathrakh
to the forefront of modern extreme music.
The only criticism here is that, with everything on overdrive all
the time, there is little room for variation.
Even with that nitpick, this is one mighty intense band.
